Article 16- Escalators and Moving Walks Based on the Installation Environment
Escalator and moving walk installation environment
In this article we intend to explain the different types of escalators based on installation environment.
Escalators and moving walks divide into three categories based on their area of installation as below:
1. Indoor Escalators
Indoor escalators and moving walks are suitable for closed environments, where there is control over the ambient temperature. Therefore, these types of escalators and moving walks are not subject to elements such as rain and snow.
2. Semi Outdoor Escalators
These types of escalators and moving walks are installed outside the building; nonetheless, they have roofs above them to protect against the direct downpour of rain and snow. Obviously, since these escalators and moving walks are outside the building, they are not in a temperature-controlled environment. Therefore, in comparison to the indoor escalators, they have a wide range of options, based on the geographic location of the installation environment. Examples of these options include cooler, which cools down the device in high-temperature situations, or heater, which heats the device in low-temperature conditions.
To enhance the performance of the escalators and moving walks, based on the geographical location and customer requirements, there are specific options to choose from.
3. Fully Outdoor Escalators
These types of escalators and moving walks are installed outside the building without any roof or other overhead covers. As a result, they are completely subject to the elements, such as rain, snow, etc. These types of products will have a wide range of options, i.e. lubrication-free rollers, water and oil drainers, etc. Even though this type of device is capable of functioning in all weather conditions, the standard recommends that they have a roof over them for safety concerns. For example, in case the escalator or moving walk does not have a roof, passengers may have to use them with their umbrellas spread over their heads in rainy or snowy conditions and this may cause them to lose balance or fall.
